SOURCE: Lamp light turns red
Yes this is the signal for a bad lamp. Other things can cause this. 1. Look at the new lamp. make sure it still looks good. not broken with little glass pieaces in it. 2. When you turn on the tv, put your ear to the lower back part of the tv near the middle. Listen for the start up of the color wheel (a low high pitch sound only at the start up of the motor). If this is good you will here a ticking sound only if the lamp dose not light.
Now with all this info. If the lamp lights (as seen from the back of the set) and goes out after a few seconds and you did not here the color wheel spin up, the color wheel is bad.
If you here the color wheel spin up and no ticking sound, the Ballast is bad.
The ballast part no. 939P978010
The color wheel is not avialable from Mits. You will have to replaced the light engine. It cost to much. Just buy a new tv.

Capacitor failure is the most likely scenario the FMT ans Signal PWB would cause the picture interference and the power pwb would cause the lamp light to turn red and give a 34 code when the device/ input and menu buttons are pressed in together and held for five seconds. That chassis has issues with every board in the chassis having failed capacitors you can get repair kits for the V26 chassis at the follwing link that come with instructions. Your model is the V26 chassis. Heres the link.
